TRAVELING CRANE.

To all whom it may concern:

Be it known that T, ARMANI) BAILLY, a Belgian subject and resident ofParis, France (post-office address 46 Quai Henri IV), have invented newand useful Improvements in Traveling Cranes, which improvements arefully set forth in the following specification.

The present invention relates to improvements in traveling cranes.

The object of the present invention is to arrange the truck of theportable crane in such a manner as to impart stability thereto when thecrane is stopped for raising heavy loads, whilst shortening the lengthof the truck in order to increase the inward range of lifting.

The accompanying drawing shows by way of example a crane provided withthe improvements forming the subject of the present invention.

Fig. 1, shows a side elevation of the crane.

Fig. 2 is a plan view thereof.

In these two figures the left half of the drawing shows the truckarrangement when the crane is held stationary for lifting heavy loads,and the right half of said drawing shows the arrangement of the truckwhen the crane is free to travel along the rails.

Figs. 3 and 4 are views in elevation of each of the ends of the crane.

These figures show clearly that the device consists in a set of fourscrew jacks combined with two removable cross-beams carrying the buffersand couplings.

In these drawings a indicates the frame of the truck, which, as usual issupported on wheels or wheeled bogies and carries the usual turntablesurmounted by the rotary frame which is equipped with all the usualhoisting setting and like devices.

At or near the corners of the frame a, are four strong sockets d whichserve for the connection, by means of pivots c, of four brackets orswinging arms f traversed by vertical screws 9 which serve to bearagainst the ground when the crane is stationary for lifting purposes.

The above-described system is well known but the present inventionprovides the following improvements The above-mentioned swinging arms 7"are provided at their extremities with connecting means it which servewhen the crane is to be moved along the rails, to hold firmly the crossbeams a carrying the couplings and bufiers.

It will thus-be seen that when the crane runs onthe rails, the swingingarms 7 are parallelto the rails and are connected two by two by a crossbeam ti, and when the crane 'is stopped for lifting heavy loads, theswinging arms fare set at right angles to the rails, and by means of thescrews '9 serve to bear against the ground and to give stability to thecrane. Moreover the cross beams i having been removed to free the swingarms f and these arms 7 being no longer in line with the truck of thecrane, an increase in the useful inward lifting span is obtained whenthe jib is in a position parallel to the rails.

For securing the arms 7 in the required position for providing stabilityor during movement of the crane, an accessory may be employed consistingof stays 7c connecting suitably situated points of attachment on theframe and arms The same stays arranged afterwards at Z may serve toreinforce the structure formed by the cross beamsz' in combination withthe arms f.

What I claim and desire to secure by Letters Patent is 1. In a travelingcrane, a truck, swinging arms pivoted about the corners of said truck,screw jacks carried by said swinging arms and removable transversebuffer beams interconnecting said swinging arms in pairs whilst saidcrane is in the traveling condition.

2. In a traveling crane a truck, swinging arms pivoted about the cornersof said truck, screw jacks carried by said swinging arms, connectingmeans on the end of said arms and removable transverse buffer beams heldby said connecting means interconnecting said swinging arms in pairswhilst said crane is in the traveling condition.

3. In a traveling crane, a truck, arms pivoted about the corners of saidtruck and swinging from a position parallel with said truck to aposition at right angles thereto, screw acks carried by said swingingarms and removable transverse buffer beams interconnecting said swingingarms in pairs whilst said crane is in the traveling condi tion.

4,. In a traveling crane, a truck, arms pivoted about the corners ofsaid truck and swinging from a position parallel with said truck to aposition at right angles thereto,

screw jacks carried by said swinging arms, connecting means on the endof saidarms and removable transverse buffer beams held by saidconnecting means interconnectlng said swinging arms in pairs whilst saidcrane is in the traveling condition. I

5. In a traveling crane, a truck, swinging arms pivoted about thecorners of said truck and swinging from a position parallel with saidtruck to a position at right angles thereto, screw jacks carried by saidswinging arms, removable transverse buffer beams in terconnecting saidswinging arms in pairs whilst said crane is in the traveling conditionand removable stays connecting said armsand said truck in each saidalternative position.

6. In a traveling crane, a truck, arms pivoted about the cornersvof saidtruck and swinging from a position parallel with said truck to aposition at right angles thereto, screw jacks carried by said swingingarms, connecting means on the end of said arms, removable transversebuffer beams held by said connecting means interconnecting said swingingarms in pairs whilst said crane is in the traveling condition andremovable stays connecting said arms and said truck in each saidalternative position.

In testimony whereof I have signed this specification in the presence ofa subscribing witness. I
